2)Test
a)Ultimate Tensile Test
Couplers have been tested by connecting rebars from different countries (including russia , france, india , japan ,iran ,korea,usa,singapore and so on). Testing results are satisfied . 100% bar break.
b)Fatigue Test
Couplers are tested uder 2 million times of fatigue strength test , and connection is in good condition.
